Image capture device with reduced fogging
An image capturing device comprises an elongated body, an imaging window coupled to a distal end of the elongated body, and a heat source within the elongated body. The heat source is configured to apply heat to the imaging window to remove condensation from or prevent condensation from forming on the imaging window.
Imaging system and control device for determining high-luminance region and reduction light amount to illuminate region
An imaging system includes an imaging device that images a predetermined imaging area, an illumination device that performs irradiation with illumination light so as to illuminate an imaging area and is capable of adjusting a light amount of the illumination light for each of local regions narrower than the imaging area, and a control unit that controls the imaging device and the illumination device. Then, a high-luminance region having a luminance value exceeding a predetermined luminance range is detected in an image captured by the imaging device, and a light amount of illumination light with which the illumination device irradiates a local region corresponding to the high-luminance region is determined to be a reduction light amount reduced to be less than a light amount with respect to overall of the imaging area. The present technology can be applied to, for example, a camera system for operation.
HEAD-MOUNTED DISPLAYING OF MAGNIFIED IMAGES LOCKED ON AN OBJECT OF INTEREST
System and method for presenting magnified images locked onto object of interest in operator environment. A camera disposed on head of operator captures images of scene, where camera moves in conjunction with head movements. A head tracker detects the operator LOS by detecting at least head orientation. A processor obtains designated coordinates of object of interest in scene, and determines relative angle between detected operator LOS and object. The processor determines coordinates of object in acquired images, and applies image processing for fine stabilization of images based on previous images so as to compensate for operator head movements. The processor rescales an image region surrounding object of interest, in accordance with at least one display parameter, to produce respective magnified image frames of object. A head-mounted display displays the magnified images to operator such that object of interest appears in a defined position on display regardless of operator head movements.
METHODS AND DEVICES FOR DETECTING BIOFILMS ON THE EYELID MARGINS
A composition for detecting biofilm on an eyelid margin includes a dye that binds to the biofilm and a solution that is biocompatible with the eye. A method for detecting biofilm on an eyelid margin of an eye includes applying a solution to the eye or the eyelid margin so that a dye in the solution binds to the biofilm. A handheld camera for detecting biofilm on an eyelid margin of an eye includes a housing, an image sensor, and a lens including a focal length determined by a distance between the lens and the eyelid margin. A method for detecting biofilm on an eyelid margin includes capturing an image of the eyelid margin using a handheld camera and determining if the biofilm is present on the eyelid margin. A system for detecting biofilm on an eyelid margin of an eye includes a composition and a handheld camera.
Device and method to standardize photography acquisition
The device and method are intended for the standardization of picture taking without contact with the subject. Two light beamers converging at a distance within the range of camera focus are enabling reproducible viewing conditions via superimposition of the spots of the beamers on the subject and the light of the beamers are extinguished during picture taking in order not to bias the image. The device is constituted of a body (1) adaptable to a camera (1) with objective (2) and is including two light beamers (4A) and (4B) whose beams (5A) and (5B) are converging at a distance (D) within the focus range of the camera as well as a mechanism to extinguish the light beamers during picture taking. It can be improved by enabling the covering of the focus ring (2) and zoom ring (8) of camera (1).

MEDICAL OBSERVATION DEVICE AND LENS BARREL OF MEDICAL OBSERVATION DEVICE
To achieve improvement in functionality resulting from switching of optical elements and miniaturization of the device. A medical observation device includes: an imaging optical system configured to capture an image of a subject; an image sensor configured to photoelectrically convert the image of the subject captured by the imaging optical system; and an element holding frame configured to hold a plurality of optical elements and to be capable of being rotated around a rotation shaft. An axial direction of the rotation shaft is set to a direction orthogonal to an optical axis direction that is a direction of a line from the imaging optical system to the image sensor, and the element holding frame is rotated and thus at least one of the optical elements among the plurality of optical elements is positioned on an optical axis.
